Dr. Tom Haard, formerly of Northwestern University, joined the Berkeley group to work on development
of the next generation superfluid rotation sensor. Haard and graduate student Emile Hoskinson recently
completed testing of a rejuvenated ultralow temperature cryostat. They were able to achieve a
significant reduction of acoustic noise generated by the so-called 1K pot by making modifications
based on work in Germany. This improvement will lower the noise level of any very low temperature
experiment whose sensitivity is limited by acoustic disturbances.

Neils Bruckner submitted his thesis on the development of an enhanced-sensitivity superfluid
phase-slip gyroscope. The new device has two orders-of-magnitude greater pick-up area than the
previously reported prototype device. Bruckner, who held a NASA fellowship during this graduate
work, also submitted a manuscript describing his gyroscope to the Journal of Applied Physics.

Ray Simmonds received his PhD degree from UC Berkeley for his work on superfluid Josephson physics.
Simmonds, who helped develop the Josephson gyroscope, received a prestigious National Research Council
Postdoctoral Fellowship to work at NIST in Boulder. During much of his thesis research, Simmonds was
supported by a NASA GSRP grant. Ray was the student responsible for doing the experiments studying
the superfluid Shapiro Effect, and for making the prototype superfluid dc-SQUID in He3. He was also
the key student contributor to the discovery of novel dissipation mechanisms in Josephson weak links.
All his work is described in the July 2002 Rev. Mod. Physics article that is on the web, but not
yet in the libraries.
